SHOCK-ABSORBER FOR VEHICLES.

Application filed. March 18, 1908. Serial No. 420,904. A

-To all whom it may concern:

Be it known that I, CLEMENT M. KENT- zINGER, a citizen of the United States of America, residing at the city'of St. Louis,

in the State of Missouri, have invented certain new and useful Improvements in Shock- Absorbers for Vehicles, of which the follow ing is a full, clear, and exact description, reference being had to the accom anying drawings,'forming art of this speci cation.

vIIII, Fig. I. Fig. III is an enlarged view partly in elevation of portions of a vehicle 4 and partly in vertical section taken through my shock absorber. Fig. IV is a top. or

- planview of the parts shown in Fig. III.

In the accompanying drawings: A designates the axles of a vehicle, B the vehicle bodyframe, and C the ordinary body frame supporting springs that are supported by the axles A. I

1 designates a main fixed bearer that is mounted upon the ordinary spring C and may beheld thereto by the usual spring holding shackles C. This bearer is rovided with an arm 2 that extends latera 1y .from andtransversely of the spring C, thereby furnishing a bearer portion that is offset from said spring.

40 \T 3 is an auxihary offset bearer extending parallel with the spring C and adapted to rest in part upon theoffset arm of the main bearer L and is provided with a vertical apertu re that receives a guide rod 4,- seated in the offset arm-20f themain bea'rer and extchdingvertically therefrom. The auxiliaryofiset bearer 3 is free of connection to the offset arm of the main bearer and is adapted to play vertically above theguide rod 4.

fidesignates a second guide rod that is "fitted in the auxiliary. offset ,bearer3 aside from the offset arm of the main bearer and which extends vertically from said auxiliary offset bearer and parallel with the guide said oifset arm upon 6 is a. bracket fixed to the vehicle body frame B and which is provided with an arm 7 that extends laterally from said body frame transversely of the spring C and the auxiliary offset bearer 3, in a position to I rec'eive the guide rod 5 which is loosely seated in an aperture in said bracket arm.

. 8 and 9 are cushion springs located respectively around the guide rods 5 and 4, the cushion spring 8 being interposed between the auxiliary oflset bearer 3 and thebracket arm 7, and the spring 9 being interposed between the auxiliary offset bearer 3 and the head 4 at,the u per end of the guide. rod 4.

The guide r0 4 is provided at its lower.

end, beneath the arm of the main bearer,

with a head or nut 4 that serves to limit the degree of upward movement of said guide rod. The guide rod 5 is provided at its upper and lower ends with heads or nuts 5 and 5.

When in the practical use of my shock absorber a round wheel of a vehicle is subjected to a low by impact with an obstruction, the following actions take place: The force of the blow is transmitted to the vehicle axle and the vehicle body frame descends, and as said body frame moves downwardly its movement is yieldingly resisted by the s55 cushion spring 8 during which the bracket arm 7 resting on said spring moves in sliding en agement with the uide rod 5. Then, as

reo'und of the vehic e body frame occurs, subsequent to thedescentpf the frame, the bracket arm 7 moves upwardly until it engages the head 5. of theguide rod 5, and after such engagement has taken place a continued movement of the body frame and bracket arm causes the auxiliary ofiset bearer 3 to be elevated and travel in sliding engagement with the guide rod 4. As the auxiliary ofiset bearer rises it acts to compress the cushion spying 9, situated around the guide rod 4, and said cushion spring by its yielding resistance to the upward movement of the auxiliary offset bearer acts to take u any shock incident to there-boundof the ody frame. It isobvious that after the actions set forth have taken place the two cushion springs Sand 9 ,will act in con-- junction, with each other, until the power in the two springs has become. equalized and the parts of the shock absorber have resumed their normal positions.

' I claim:

The combination, with an axle, body tween the head of the latter and the inner frame, end hody frame supporting spring passed through the inner end of the auxiliary oflset arm and secured'to' the offset arm of the main bearer, a cushion spring surroundingthe upwardiy extending guide r0d,' beend of the auxiliary offset bearer, a bracket emae'e rod having a. head and passed throughi'the 15 outer end of the auxiliary bearer arm and secured tothe bracket 2min and a cushion epmng surroundmg the. auxiliary guide rod between the outer end of the auxiliary bearer end the bracket arm.
